According to a recent investigation published in Electronic
Internationnal, ARM core processors are present in 76.8% of embedded
systems (against 57.8% in 1999!) - 539 Millions of core selled, MIPS
10.9%, Hitachi SH 7.2%, PowerPC
3%, others (including x86) 2.1%.
Ok, they don’t tell how many selled core are equiped with MMU!
But, according to a ARM data sheet, on 45 existing ARM processors, 20
own a MMU.
So actually, qrtp cannot aspire, with all your effort to support more
than 50 processors (today), to more than 16% of embedded market!
Strange for an embedded capable OS!
What about the others 76,8%?
Today, more 20 RTOS run on ARM and of course your main rivals are there!

Be careful with these sorts of statistics as they can be very misleading
unless they specifically also breakdown 8, 16 and 32 bit processors and
microcontrollers. With respect to ARM, many of the ARM cores used in
high volume devices do not have an MMU (e.g. ARM 7). However, we
are seeing more of these devices planning use of ARM cores with MMUs
(e.g. ARM 720, ARM 920, etc). This is where QNX will paly very well.
QNX has and will release support for x86, PowerPC, MIPS, ARM/StrongARM
and SH4 (all with MMUs of course)
I think you need to be careful with such statistics, because it all depends on just what you mean by an “embedded system”. If you simply mean some kind of device with a microprocessor inside it, you’ll find that the vast majority contain 8-bit and 4-bit processors, most of them with no OS of any kind. Clearly the article you refer to targeted some sub-set of embedded systems. It would be well to know just what sub-set they used.
Hi,

Why not you?
Just don’t forget to actually make it available when you add it to
supported list
Apparently you have ARM and SH support for a while, but it never was
available either for free or for money, not even as beta to the best of
my knowledge.
